To all whom it may concern:-

Be it known that l, Bonner ject of the King of Bavaria, and resident of Plauen, Germany. engineer have invented new and useful Improvements in JacquardCardPunchmg Machines, of which the following is a full, clear, and exact specification. I

The on s used in working a jacquard emlnoidering machine are perforated, as is well known, with holes in accordance With the length of the various stitches, in a so called card punching machine, whereby the separitc stitches are decomposed into components in twogiven directions by means of a cross-slide end are transmitted in each component direction to the card punching mechanism by means of a particular punch selecting device. The most Zirnn, a suban adjustable selector designed to he adjusted according to the length of the stitches and which consists o't pin wheels or pin drums, in the present well known machines of this kind.

The present invention relates to jacquard card punching machines of this kind and consists in an improved punch selecting device comprising for the stitch transmission control in one component direction a movable punch selecting member capable of being); adjusted on either side of a zero position and having; holes and slots constituting a pattern scale on both sides of a zero line means to operate said punch selecting men1- her according to the stitch length to be trai'ismitted in the respective component direction and an automatic returning mechanism. arranged to restore the punch selecting member at the end of every stitch movement, when this has operated a corresponding punch selection, positively back into its The accompanying diagrammatic drawing shows a method of carrying out the in vention and also two modifications of the punch selecting or perforation determining Figure 1 shows the complete arrangement mounted on a jacquardcardpunching inachiuc. Fi 2 and I show the punch selectiug or pcrloration determining member oiv this m'rangcmeu in front elevation and in plan rcs iiectively. and Figs. l, and (3 7 show lhetwo modificationsmentioned above.

1 (Fig. l) is the 'ftll'd to beperi'o ated,

which is intermittently drawn forward uninmortant part ofsuch a selecting device 1s torution determinin b d or the punch box 3 carrying the punches 2, so as to be perforated by the said punches. The punch box 3 is adapted to be raised and lowered from time to time by means of a lever 4t. V l

The punches 2 may be rigidly coupled in a selective manner to the punch box 3 by means oi lifting bars 5 which are controlled by selecting pins 6 and may be coupled upon a driving lever 7 according totheir respective 1:)OSltl011S, so that they may be shifted forward by the lever in the punch loo); The pins (3 are held in a vertically movable carrying piece 8 which may he moved from time to time by a lever 9. These parts belong to the partic ular card punching mechanism.

7 to lock the punches 10 is the pattern board on which the dc 4 needle ll is corresign is fixed. The guide the design by the spondingly moved over operator controlling the handle 12. Tn this operation the frame 13 follows each movement in the horizontal direction, that is to say, has the horizontal component. of each stitch imparted. to it. The rack 14 imparts the movement of the frame 13 to the pinion 15 and through tat rack 17 which is connected to the peror punch selecting member 18. The latter consists of a horizontally guided reciprocating slide which is movable under the selecting pins 6 to either side of a given zero line. This slide 18 as may best be seen from Fig. 3, is provided with a pattern scale of holes and slots which is arranged symmetrically on both sides of a zero point marked by the line I, on which there is no hole or slot and which lies immediately below the row of selecting pins 6.

T he holes and slots on the slide forming the scale are arranged in es rows as there are pins 6 so that for each pin 6 there is acorrcsponding longitudinal scale row, and further the holes of one longiu tudinal hole row are longitudinally displaced relatively to the corresponding holes in the neighboring hole row by a space equal on the pitch of the teeth on the rack 17.

The perforation determining or punch se looting slide 118 is temporarily ,held in the adjusted positionhy means oi? a locking; lever many longitudinal 19 which is brought into engagement a that moment with the pinion 16 ment of a. lever 20. y

In order to bring the perforation deter,- mining or punch selecting slide 18 back into by the u ovethe pinion 16 to the horizonits zero position in a positive manner and very exactly, a pair of returning nipperaws 21 is arranged over the rack 17, which "is normally open, but can be periodically closed by means of a lever 22 and link 23 upon a pin 24 on the rack 17, which stands vertically below the pivoting point of the nipper-jaws 21. in the zero position of the slide 18. It may easily be understood that when the pin 2st has been moved to either side of the vertical through the pivoting point of the nipperqaws, owing to the movement of the $11 e 18, it Will, together with theslide '18, be positively brought back by the closing of the nipper-jaws into the normal position, so that the slide '18 is again -9, 20, 22 and 9.3 are coi'itiblled bar 5 over the corresponding punch '3 lock the latter in the punch box I). lnune-" d atcly afterward the punch box 3 with the brought into its exact zero position. This returning of the perforation determining or punch selecting slide 18 only operates after the levers take place 'at their proper times in the order set forth below. 'llic-cam disk 28 turns in the direct ion of the arrow indicated in Fig. l and is so driven that it makes one revolution for every complete cycle of operations.

The 0 ieration oi. the whole arran ement is as follows: it a movement is executed on the design with the guide needle 11, so that the horizontal component of a stitch movement is imparted to the frame 13, the rack 17 pushes the perforation determining or punch selecting slide 18 away from its zero position to one side or the other, and the lockinglever 19 is then forced into cngagement with the pinion 16 by the action of the cam groove 20 on the lever 20 so that the slide 18 is held fast in its new position. Should for instan'cethe slide 18 be thrust toward the left a distance corresponding to four consecutive teeth divisions of the rack 17, then the hole a: (Fig. 3) of the slide will be under the vertical row of pins (3. 'lhevpm carrying piece 8 with the pins 6 is now lowered owing to the action of the cam slot 5) on the lever 9, whereby the pin ti which happens to be opposite the hole H}, enters the latter and allows the tilting bar 5 resting upon it to drop down, so that this latter is coupled upon thelcver 7. The lever 7 is then-swung out by the action of the cam roo \',.e"t' and thereby pushes the coupled to punches 2 is lowered by the action ot' the cam groove t" on the lever 4 and the punch locked or coupled to it stamps out a hole in the card corresponding to the position of the slide 18. 'After the punch box has been again raised, the card is fed forward one step by a pawl mechanism, not illustrated, while the lever'tpulls back the coupled bar 5. The pin carrying piece 8 then returns to its upper position while the rack 17 is disengaged from the pinion It by the action of the cam groove m the lever 25. The lever 22 is nowso actuatcd'by the am groove 22 that the nipper-aws 21 are closed whereby the disengaged rack 17, and with it the perforation determining or punch sclecfing sIide lS, is necessarily brought back exactly into the initiator zero position. The nipper-jaws 21 now again open, the rack 17 is again brought into engagement with the pinion 1t and finally the locking lever 15) is brought out of engagement with this pinion. lh,e cam disk QH'has completed a full revolution during the above operations and it can again begin the cycle ot.- oper, ations when the perforation determining or punch selecting member is again moved.

in the modification according to Figs. 4 and the perforation determining or punch selecting drum 18' whose peripheral surface is provided with the same pattern of holes and slots as that illustrated in Fig. 3.

According to l igs. ti and T the perforalion determining or punch selectingmember consists of a revoluble circular disk18" which is also provided with a pattern or scale consisting of holes and slots arranged symmetrically on both sides of a zero position marked by line I.

In the first n'iodification the row of selecting pins is arranged along agenerating line of the drum 18, while in the second modification it is arranged along a radius of the circular disk .18. In the same way similar members transmit the vertical components of the stitches to a punching mechanism and through it to the card, a corresponding perforation determining or punch selecting member being provided so as to move acmember consists of a revoluble cording to the components of the stitchv movements in the vertical component (1i:- rect'ion.
